Yes, this sounds very natural and professional.

Hi Alexiane, It's difficult to say, it sounds almost right but maybe not quite "natural." Then again, cover letters never sound really natural so I wouldn't worry too much. I looked at one of my cover letters and I ended it with "I look forward to the opportunity of talking with you further. Thank you for your consideration." I'm not even sure I like my own in hindsight, but I found a job so I guess it worked out. I think those two work can work together, but I would probably change it to "I look" instead of "I am looking." I looked at some sample cover letters my school offers and they finish with "I would welcome the opportunity to interview with ____(you/your company/your office). Thank you for your time and consideration."
